Embodiment Construction

[0032] The power path test of the pyrotechnic device involved in the present invention includes three parts: the internal power path test of the pyrotechnic device controller, the external path test of the pyrotechnic device, and the internal and external connection relationship test. The internal power path test mainly refers to the current limiting resistance in the controller. Test, the external path test mainly refers to the path resistance test of the cable network and the pyrotechnic load, and the connection relationship test refers to the correctness test of the connection between the controller and the external cable network.

[0033] The key points of the internal path test and the connection relationship test are: after the internal path test is completed, the connection between the external power cable and the controller is restored, and the verifiability of the connection relationship; the key points of the external power path test are: the installation position of t...

Abstract

The invention discloses a method for testing the pathway of satellite initiating explosive devices, comprising a plurality of initiating explosive devices, controllers of the initiating explosive devices, test plugs, adapter plugs, and adapter cables. The controllers of the initiating explosive devices are connected to N initiating explosive devices through test plugs, adapter plugs, and adapter cables to complete the internal power pathway test of the controllers, the internal and external connection test of the initiating explosive devices, and the external pathway test of the initiating explosive devices. According to the method for testing the pathway of satellite initiating explosive devices, the consistency of the pathway object of initiating explosive devices and the design file canbe verified, the test result has the characteristics of reproducible and re-checkable, and has been applied on multiple communication satellites, thereby effectively ensuring the safety and correctness of the pathway of initiating explosive devices.

Description

technical field [0001] The invention relates to a method for testing the passage of a satellite pyrotechnic product. Background technique [0002] The pyrotechnics for satellites are pyrotechnic devices that control movable parts such as satellite solar wings, antennas, and propulsion pipeline valves. The correctness of the pyrotechnics passage directly affects the success or failure of the flight mission. It is an important line of defense to ensure the normal work of star pyrotechnics in orbit. [0003] my country has accumulated rich experience in pyrotechnics testing during decades of satellite development, and some of the experience has been passed down to this day. With the rapid development of electronic components, relays are gradually replaced by MOS tubes, satellite pyrotechnic controllers have undergone state upgrades, and new forms such as multi-channel parallel connections have appeared in pyrotechnic product paths. The traditional pyrotechnic product path test...
